[LRUG] which blog and which BB?

[Ed Davey]

I am making a site in Rails which will include amongst other things a  
blog and a discussion forum.

For the blog I plan to use Typo (familiar with Typo 4) but am not  
sure about the forums.

As far I know there aren't any mature, stable, well documented ruby  
or rails BBs? I've used SMF (yuck) in the past and I know that people  
have integrated punBB with rails:

http://weblog.terrellrussell.com/2008/01/generating-a-rails-and-punbb- 
and-dokuwiki-shared-cookie/

and that railsforum.com use punBB.

Any recommendations / comments on either / both the blog and  
discussion forum application areas?

Eg

- how suitable are Mephisto and Beast given that I want to be up and  
running fast and am no jedi
- experiences using Typo 5 in production

Thanks

ED
